2016 ACS 1-Year Public Use Microdata Sample (PUMS) Files

The PUMS files show the full range of population and housing unit responses collected on individual ACS questionnaires for a subsample of ACS housing units and group quarters persons (approximately one percent of the United States population).

The PUMS files allow data users to conduct a custom analysis. Working with PUMS data generally involves downloading large datasets onto a local computer and analyzing the data using statistical software such as R, SPSS, Stata, or SAS.

2016 ACS 1-Year Supplemental Estimates

The ACS is the most relied-on source for up-to-date social, economic, housing, and demographic information every year. Supplemental Estimates provide these data for geographies with populations of 20,000 or more, compared to the 65,000 population minimum for the standard ACS 1-year estimates. They are available for the nation, all 50 states, the District of Columbia, Puerto Rico, every congressional district, every metropolitan area, and all counties and places with populations of 20,000 or more.
